1) In the expression toot [one's] own horn, which means to praise oneself. Often in the form "I don't want to toot my own horn, but [...]".
2) A cutesy word for a fart, used primarily when talking to young children.
Notably, an elephant using its trunk to make noise is said to be trumpeting, not tooting.
So if Mr Trump was on Mastodon would we say he was tooting or trumpeting?
And, for many people, it's the only meaning that naturally comes to mind in phrases like "I tooted" or "Joe tooted".
Kids impersonating the noise a train horn makes.
A word for farting.
The only context in which you'd normally say that someone "tooted" is the latter.

Not everything is a cynical ploy. There are still pure and wholesome things in this world.
